    The driving mode of the valve can be selected according to the actual working conditions. If necessary, the supplier can provide technical support.
    1. Automatic valves are valves that do not require external force to drive, but rely on the energy of the medium to make the valve act. Such as safety valves, pressure reducing valves, traps, check valves, automatic regulating valves and so on.
    2. Power-driven valve: Power-driven valve can be driven by various power sources.
    For example: electric valve: a valve driven by electricity. Pneumatic valve: A valve driven by compressed air. Hydraulic valve: Valve driven by the pressure of liquid such as oil.
    In addition, there are several combinations of the above driving methods, such as gas-electric valve.
    3, manual valve: manual valve with the help of handwheels, handles, levers, sprocket, manual valve operation. When the valve opening and closing torque is large, this wheel or worm gear reducer can be set between the handwheel and the valve stem. When necessary, you can also use the universal joint and drive shaft for long-distance operation.
